Frontline Chaos is a Total Conversion mod for C&C Generals Zero Hour. It will replace the original sides, and introduce two brand new armies: Revenant and Legion. The mod's goals are to supply a completely new story, including campaigns for both sides, and a balanced and fun multiplayer experience.

In case you haven't noticed: I try to design my own stuff, or base it upon old stuff. The Challenger / Abrams / Leopard / any-other-currently-popular-main-battle-tank has been made so many times that it ain't funny anymore.
They also wouldn't fit with the story.
